GHG17 DD Medium Duty Operators Manual 2. Add oil to maintain the correct level on the dipstick. Use only the heavy- duty oils recommended in the "How to Replace the Lubricating Oil and Oil Filter" section in this manual. NOTE: If the dipstick has a positive locking device such as a lever or twist- lock design, this must be disengaged before pulling the dipstick out of the guide tube. 3. Remove the dipstick from the guide tube. Use a shop rag to wipe off the end of the dipstick. 4. Wait 15 seconds to allow any crankcase pressure to dissipate through the guide tube and let the oil level settle in the oil pan. 5. Reinstall the dipstick and make sure it is fully inserted into the guide tube. 6.
Remove the dipstick and read the oil level dipstick. 7. The figure shows a comparison between the bends on the dipstick and a crosshatch pattern on a conventional dipstick. Note the exact area noted on the bends. For example, the 'maximum' oil level will be at the BOTTOM of bend (1). For the 'minimum' oil level, it is noted at the TOP of bend (2). If the oil level is below the 'minimum' bend, add oil to bring it up the 'maximum' level. Do NOT fill beyond the maximum fill level on the dipstick, since overfilling may result in high oil consumption and possible severe engine damage.
